About Lab Grown Diamonds
A radiant marries an emerald's trimmed-corner outline with brilliant faceting, so it throws lively sparkle while keeping a bold rectangular footprint. The cropped corners are structurally tough and seat securely in prong or halo settings.
Every Signora Jewels diamond is grown in a controlled lab using the CVD process, producing a stone that is chemically, optically, and physically identical to a mined diamond — same hardness, same fire, graded on the same 4C scale. Because the supply chain is short and traceable, you get a larger, cleaner stone for the same budget and a documented origin, with no mining footprint. The result is a diamond that looks and tests exactly as a natural one, with more carat and clarity for your money.
